Revalco - 1RDT3 - Earth Leakage Relay, 30mA-3A, 230VAC

The Revalco 1RDT3 is an earth leakage relay designed to monitor and protect electrical systems by detecting ground fault currents. Key features include:

• Trip Current Adjustment (IΔN): Selectable settings at 30mA, 300mA, and 3A, allowing flexibility to suit various protection requirements.

• Time Delay Adjustment: Configurable delay times of 0, 0.2, 0.5, 3, and 5 seconds, enabling coordination with other protective devices and preventing nuisance tripping.

• Auxiliary Power Supply: Operates on 230VAC ±10%, 40/60 Hz, compatible with standard industrial power supplies.

• Output Relay: Equipped with one change-over contact rated at 10A, 250V, facilitating integration with alarm systems or circuit breakers.

• Signaling LEDs:

• Fault (Red LED): Indicates relay activation due to an over-limit condition after the set time delay.

• On (Green LED): Confirms the device is correctly powered.

• Test and Reset Functions: Front-accessible push buttons for testing the relay’s functionality and resetting after a fault condition, ensuring ease of maintenance.

• Protection Class: IP20 on terminals and IP40 on the front, providing adequate protection against dust and solid objects.

• Mounting: Designed for DIN rail installation, occupying 3 DIN modules, which simplifies integration into electrical panels.

• Standards Compliance: Conforms to IEC 364 / 4-5, IEC 755, CEI EN 60947.2/B, CEI 64.8, and CEI EN 61008/1, ensuring adherence to international safety and performance standards.
